Alex have 200 cards.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
According to the question
Alex, Gil and Meg shared 740 cards.
Alex had 20 fewer cards than Gil and 120 fewer cards than Meg.
Assuming Alex have x cards
Based on the given condition, write equation
[tex]x+(x+20)+(x+120)=740[/tex]
Solving the equation
[tex]3x =740-20-120[/tex]
[tex]3x=600[/tex]
[tex]x=200[/tex]
Hence, Alex have 200 cards.
